My only problem with the FieldPro system with my 8x42 Nl has been the fragile objective covers, which have torn away twice in the best 2 months, at the point where the cover meets the bezel of the objective. This seems to happen almost spontaneously with almost no use. I can leave the objective covers open and leave the binoclars resting horizontally on a table overnight. I return in the morning and the cover has torn away. I don't think I am alone with this problem. The service rep at Swarovski tells me he gets 3 calls a day about the same problem. They happily replace them, but there is an obvious problem with the rubber of these covers.
